Clinical characterization of 3-month-old pigs infected with African swine fever virus from Vietnam
African swine fever (ASF) is a fatal viral disease in pigs, with a short incubation period and causing immediate death. Few studies exist on the Asian epidemic ASF virus (ASFV) challenge in older pigs, including growing and fattening pigs and sows. We aimed to investigate clinical outcomes, pathomorphological lesions, and viral distribution in organs of 3-month-old growing pigs that were inoculated with the ASFV isolated in Vietnam. The clinical outcomes were recorded daily, and the dead or euthanized pigs immediately underwent necropsy. Viral loads were determined in 10 major organs using qua...

Investigation on the asymptomatic endometriosis of Korean indigenous cow in Gyeongsangnam-do
Reproductive disorders in cows cause economic loss in livestock farms. This study was carried out to investigate the incidence of endometriosis in the uterine of Korean indigenous cow (Hanwoo). In the present study, the uterine of 25 cows was provided by the slaughterhouse. As a result on a visual examination of the uterus, 18 out of 25 were visually normal, and 7 uteruses (28%) appeared rather pale and showed purulent or mucosal symptoms in Uterine horn. However, the results of hematological analysis showed that both RBC and WBC were normal and showed no signs of systemic inflammation, indica...

Prevalence and co-infection status of three pathogenic porcine circoviruses (PCV2, PCV3, and PCV4) by a newly established triplex real-time polymerase chain reaction assay
A novel porcine circovirus 4 (PCV4) was recently emerged in Chinese and Korean pig herds, which provided epidemiological situation where three pathogenic PCVs, PCV2, PCV3, and newly emerged PCV4, could co-infect pig herds in these countries. In this study, a new triplex quantitative real-time polymerase chain reaction (tqPCR) method was developed for the rapid and differential detection of these viruses. The assay specifically amplified each viral capsid gene, whereas no other porcine pathogenic genes were detected. The detection limit of the assay was below 10 copies/μL and the assay showe...

Epidemiologic investigation of gastrointestinal pathogens for Korean cats with digestive sign
This study was performed to investigate infectious gastrointestinal diseases in 115 Korean cats (83 indoors and 32 outdoors) with digestive signs such as diarrhea, anorexia or abdominal distention. Detection of infectious pathogens was analyzed using real-time PCR. As a result, 85 of 115 Korean cats were detected with feline corona virus (FCoV), feline parvo virus, Group A rotavirus, Clostridium perfringens (C. perfringens), Campylobacter coli (C. coli), Campylobacter jejuni, enterotoxigenic Escherichia coli, enteropathogenic Escherichia coli, Salmonella spp., Tritrichomonas foetus, Cyclospora...

Odor reduction effect of microbially activated peat in broiler houses
The purpose of this study is to evaluate the reduction effect of microbially activated peat on odor generated by livestock farms. The odor gas was measured by stirring the livestock manure sample with the existing litter and the microbially activated peat (Healtha Peat) was developed by this research team. In outdoor farm experiment, the measurements were performed by comparing broilers farm using rice husks and microbially activated peat as litter. The weight, mortality, shipment date, and odor levels (NH3) were measured before and after experiment. The result showed that NH3 levels were redu...

Application of chemical treatment for cattle and chicken carcasses for the control of livestock infectious diseases
In the event of an outbreak of a livestock epidemic, it has been considered that the existing burialcentered carcass disposal method should be improved ecofriendly for prevention of leachate and odors from burial basically in regard of pathogen inactivation. Therefore, the aim of this study is whether it was possible to treat the carcass of cattle and chickens using the chemical carcass treatment method. It was conducted to establish detailed treatment standards for the chemical treatment method of cattle and chicken carcasses based on the results of the proof of the absence of infectious dise...

Analysis on antibody titer of structural protein after vaccination against foot-and-mouth disease virus (Type O) in zoo animals
The purpose of this study was to examine antibody titers to structural protein (SP) of the foot-andmouth disease (FMD) virus after vaccination in animals of the Seoul zoo. After the initial inoculation of FMD vaccine to the susceptible animals of the zoo, a total of 235 blood samples were collected from 42 species of zoo animals during treatment or necropsy. All samples were tested by using enzyme- linked immunosorbent assay (ELISA). The overall positive rate of SP antibodies against FMD virus was 94.0% (221/235). However, the positive rates varied according to animal species. The results of p...

Serological and molecular prevalence of lumpy skin disease virus in Korean water deer, native and dairy cattle in Korea
Lumpy skin disease (LSD) is a severe cross-border infectious disease that causes fever, skin and visceral nodules in cattle. LSD is caused by the lumpy skin disease virus (LSDV), a dsDNA virus that belongs to the genus Capripoxvirus. Although LSD has been found only in Southern Africa traditionally, in the last decade it is spreading very quickly through the Middle East and into Eastern Europe and China. It usually affects cattle and water buffalos being transmitted by blood-feeding insects. As it causes a huge economic impact, LSD is a notifiable disease by World Organisation for Animal Healt...

Treatment of central diabetes insipidus with anemia in a dog
A 10-year-old, spayed female miniature schnauzer was referred to the Veterinary Medical Teaching Hospital of Chungnam National University due to evaluation of sudden polyuria (PU) and, polydipsia (PD) (540 mL/kg/day) with severe anemia and weight loss. Blood examination results were normal except for severe anemia (hematocrit, [HCT]: 11.8%). Urinalysis revealed a urine specific gravity (USG) of 1.003, whereas urine sediment was not specific. Urine osmolality was 90 mOsm (reference range: 800∼2500 mOsm), and plasma osmolality was 303 mOsm. No specific lesions were found using diagnostic imagi...
